Factors associated with total restrictions on smoking at work and at home: a study among populations in multiple US states and the US Virgin Islands.

This study investigated factors associated with smoking restrictions in the workplace and at home in order to better understand the effects of workplace smoking restrictions. Data from the 2006 Behavior Risk Factor Surveillance System were analyzed. Multiple logistic regression was used to determine independent risk factors for potential smoking exposure at work and at home. The population potentially exposed at work were more likely to be young, male, low-income, Latino adults without college degrees or health insurance; they were also more likely to be a current or former smoker and be at risk for heavy drinking. Our study also investigated self-reported restrictions at home and found significant disparities between populations. We conclude that men, Latinos, and young adults are more likely to live in a home with a smoking ban, but are disproportionately exposed to risks at work, presumably against their preferences. Workplace smoking restrictions in 2006 offered unequal protection.
